You may not be getting enough fuel. It may be time to remove that carb and give it a good cleaning. How is your choke working, is it fully operational? If you adjust you idle control screw, does it run better?

Hi Guys,I took the carb off yesterday and it looked great inside,i went ahead and cleaned it and put it back on but it still is doing it.The choke works great.I have turned the idle screw up and it did make it idle higher but didnt make it run any better so i turned it back down,i checked the vacume line also and it was clear,im running out of ideals...lol,Any help would be great.Also what is the gap on this spark plug?Im gonna go ahead and change it but i dont think this will help but it cant hurt.Thanks for your help.

Do you have an owners manual, it should have the plug gap specs. How is your air cleaner? Have you moved to a higher or lower elevation since the last time you rode it? What does your spark plug look like now?

when mine did that I too thought fuel and even rebuilt carb. replace the spark plug and still popping, I decided to replace the spark plug boot and problem was solved. there is a resister in it that goes bad.
